Calculator to convert Amperes to kVA online with explanation of the formula and table of equivalences .

In addition, some examples are shown that clarify the conversion and the steps of how to convert from Amperes to kVA.

Amp. to kVA calculation formula for generator and transformer, AC, 3 phase, 2 phase, 1 phase:

formula Amps to kVA
  • IAC=Ampere.
  • VL-L=Volts Line-Line.
  • VL-N=Volts Line-Neutral.
  • IAC1Ø=Current/Ampere 1 phase.
  • IAC2Ø=Current/Ampere 2 phase.
  • IAC3Ø=Current/Ampere 3 phase.

How to convert Amp. to kVA in only 1 step:

How to convert Amperes to kVA in only 1 step

Step 1:

Multiply the amps by the voltage indicated in the formula and divide them by 1000. For example, a three-phase fan (3P) has a current of 10 A with a voltage of 208 VL-L, multiply 10 A by the voltage of 208 V , the root of three and divide by 1000, which will result in: 3,6kVA. (10Ax208Vx√3) / 1000 = 3,6kVA).

Examples of Amps to kVA conversions:

Example 1:

A monophasic hair dryer has an amperage of 2 Amp and a voltage of 110V, how much power in kVA will the dryer have ?.

Answer: // The only thing to do is multiply the Amps by the voltage and the result divide it by 1000, in the following way: (2Ampx110V) / 1000 = 0.22kVA.

Example 2:

A three-phase industrial juice extractor has an amperage of 1, amperes and a voltage of 208V (Volts LL), how many kVA will the extractor have?

Answer: // To know the result, you must multiply the voltage by the amperage and by the root of three, and then divide the result by 1000, in the following way: (1.4Ampx208Vx√3) / 1000 = 0.5kVA

Example 3:

A three-phase washing machine for a hotel, has a 4Amp amperage and a voltage of 220Volts (Volts Linea-Linea), how many kVA will the washing machine have?

Answer: // As in the previous examples we must multiply 4 amperex220Voltsx√3, the result of this multiplication should be divided by 1000, for a result of: 1,52kVA
